(Comprehensive foreign news reports from Los Angeles County on the 9th) Wildfires are raging in southern California, burning all the way to Ventura County and Los Angeles County. Developers continue to develop land that is vulnerable to natural disasters, making the Southern California wildfire one of the most destructive forest fires in decades.

"Time Magazine" (TIME) reported that in some ways, the Southern California wildfires are unusual. These wildfires occur late in the year when weather conditions typically suppress potential ignition, and some are in densely populated urban areas, far away from areas where fires usually start. The main reason is that dry conditions combined with Santa Ana foehn winds fan the fires.

In Southern California, Santa Ana foehn winds often blow from October to March. The warm air blowing from the desert area makes the area very windy. At its strongest, the winds can also batter the area, knocking down trees and power poles. Foehn wind temperatures also cause plants to dry out, making them more susceptible to burning. When a fire breaks out, wind can also help the fire spread quickly to various places.

Scientists said that the above situation has happened in Southern California recently. At least four fires have burned across Ventura County and Los Angeles County, forcing thousands of residents to evacuate and closing some sections of several highways.

High temperature and dry weather have also led to the rapid spread of wildfires in California. This year is the second warmest on record, according to mid-year measurement reports. According to the National Weather Service, downtown Los Angeles has received just 0.11 inches (2.794 millimeters) of rain since October, which is typically the area's wettest season.

As temperatures rise, scientists say the number of wildfires in vulnerable areas like California is expected to surge in the coming decades as warmer temperatures dry out plants and make them more susceptible to burning. The effect of climate change on the Santa Ana foehns is still uncertain, but a 2006 report published in the American scientific journal Geophysical Research Letters pointed out that warming may change the seasons in which foehns occur, causing more areas to be reduced to infernos.

Southern California wildfires should serve as a wake-up call, scientists say.
